Expect Major Travel Delays on I-5 and SR520 This Weekend

Drivers should plan ahead to avoid major traffic delays this weekend.

Weekend drivers need to plan for long travel delays and added congestion as two major construction projects are underway in Seattle and Bellevue this weekend, Aug. 25-28.

#ReviveI5 lane reductions on northbound Interstate 5 between Tukwila and Seattle and a full closure of State Route 520 between Seattle and Bellevue will also add congestion to interstates 90 and 405 as drivers try to avoid the closures.

“These delays will be widespread and we need drivers to plan their weekend trips well in advance,” said WSDOT Traffic Engineer Mike Swires. “Have a plan A, B and C and stay engaged for updated travel delays through the weekend.”
